Connecticut Security Deposit Return Letter
When a tenancy ends, a Connecticut landlord has a set time to return the deposit or send an itemized list of deductions. Here’s what Connecticut’s statute says.

Security deposits in Connecticut
Connecticut caps the security deposit at two months’ rent, or one month’s rent if the tenant is 62 or older. A landlord already holding more than one month from a tenant who turns 62 must refund the excess on request (§47a-21(b)).
- Escrow account — The full deposit must go immediately into an escrow account at a Connecticut financial institution. Within 30 days of receiving it, the landlord must tell the tenant in writing how much is held and the name and address of the institution (§47a-21(h)).
- Mandatory interest — Deposits earn interest at no less than the annual “deposit index” set by the Banking Commissioner (0.49% for 2026), paid or credited on each anniversary of the tenancy. A lease can’t waive it (§§47a-21(i), 47a-4).
- Return deadline — The landlord must return the deposit plus interest, or the balance with an itemized written statement of damages, within 21 days after the tenancy ends or 15 days after receiving the tenant’s forwarding address in writing — whichever is later (§47a-21(d)).
- Penalty — A landlord who misses the deadline is liable for twice the deposit; if the only failure is unpaid interest, the penalty is the greater of $10 or twice the interest (§47a-21(d)).
- Walk-through — Before move-in, the landlord must offer the tenant a walk-through using the Department of Housing’s checklist, signed by both sides; the landlord can’t later charge the deposit for conditions recorded on it (§47a-7c).

- Protected-tenant notice — In buildings with five or more units, the DOH notice of senior and disability eviction protections must be given at signing and at every renewal (§47a-23c).

- Deposit escrow notice — The amount held and the bank’s name and address, within 30 days of receiving the deposit (§47a-21).
Connecticut Security Deposit Return Letter FAQs
How much can a landlord charge for a security deposit in Connecticut?
No more than two months’ rent — or one month’s rent if the tenant is 62 or older. A landlord holding more than one month from a tenant who later turns 62 must refund the excess on request. The deposit must sit in an escrow account and earns mandatory annual interest (C.G.S. §47a-21).

The later of 21 days after the tenancy ends or 15 days after receiving the tenant’s forwarding address in writing. The landlord must return the deposit with interest, or the balance with an itemized list of damages. Missing the deadline can cost twice the deposit (§47a-21(d)).
